894 Datasheet, PDF (1/5 Pages) List of Unclassifed Manufacturers – AC test signal voltage adjustable up to 2 Vrms

Data Sheet
500 kHz / 1 MHz Precision LCR Meter
Models 894 & 895
Industry-Leading Performance
The 894 and 895 are high accuracy LCR meters
capable of measuring inductance, capacitance,
and resistance of components and materials at
DC or from 20 Hz to 500 kHz or 1 MHz
respectively. These LCR meters provide flexible
AC and DC test signal configuration. AC test
signal voltage is variable from 5 mVrms to
2 Vrms, the AC current is adjustable up to
66.7 mArms, depending on the AC impedance
selected, and a DC bias signal can be added. The
vivid 4.3-inch TFT LCD offers a clear view of all
measured and setting values along with BIN
sorting comparator results and a handy Zoom
feature that enlarges the measured values to full
screen. With a basic accuracy of 0.05%, auto
level control (ALC), open / short / load correction
and cable length compensation, these meter are
perfect tools for R&D, manufacturing and quality
control applications.
DC Biasing
Both the 894 and 895 feature a DC bias source
which allows the meter to apply a DC signal
to the device under test to simulate in-circuit
conditions.
DC biasing is commonly used to measure
capacitance of ceramic, MLCC, polyester and
other capacitors with high dielectric constants.
These type of capacitors exhibit a significant
change in capacitance with a DC voltage applied.
By controlling the DC voltage, users can obtain
a more deterministic measurement result. Other
applications include evaluation of
cored-inductors and junction capacitance of
semiconductor devices.
The DC bias source is adjustable from -5V to +5V
/ -50 mA to +50 mA. Additionally the voltage
or current levels can be swept while logging the
resulting capacitance.
